Mt. Gambier (Environmental Association 1.3.5)

location map showing Mt. Gambier (Environmental Association 1.3.5)

A gently sloping ash plain with steep ash cones rising abruptly. The craters of these cones contain lakes. The natural vegetation has been replaced with pastures and crops. Dairy and beef cattle are grazed, and vegetables cultivated on small holdings. Rural land merges with the urban fringe of Mount Gambier.

From the plain, the volcanic cones are dominating features, and form the backdrop for the town of Mount Gambier and the surrounding detailed rural scenes. In turn the cones provide panoramic views of this and adjacent associations, and foreground enclosed views occur within the craters.
